DERAILING DEVICE.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed May 25, 1914. Serial No. 840,686.

To all whom it may concern:

Be it known that I, JOHN A. BODKIN, a citizen of the United States, residing at New York, county of New York, State of New York, have invented a certain new and useful Improvement in Derailing Devices, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its objects to produce an improved device for derailing railway cars which shall relieve the wheel flanges from carrying the weight of the car as the flanges are lifted across the rail; to

permit a car to be run backward over the mechanism for the derailing derailing device without being derailed; to provide simple and novel means for mounting a derailing block; and to provide a simple and eflicient operating and locking block.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a top plan view of a derailing mechanism constructed and mounted in operative relation to a rail in accordance with a preferred form of my invention;

Fig. 2 is an end elevation of the device as shown in Fig. 1, the rail being in section; and

Fig. 8 is a sectional view on the line 3-3 of Fig. 2, the rail being omitted.

'Referring to the drawings, 1 represents a block which may convenientlytbe made in i i the form of a casting, the under side of the block being simply a plane surface so as to permit the block to rest firmly upon the top of a railway rail. If desired, one edge of the block may be provided with a slight of the rail, inclined upwardly from the extreme ends as indicated at 8 and 4; the surfaces 3 and i constituting tread surfaces on which a car wheel may run. Between the ends of the main body of the block and at the inner side thereof is a lateral extension divided into two parts by a diagonal rib, 5, which starts at the front inner corner of the extension and extends outwardly and upwardly until it merges with the rear end portion 4. The rib 5 forms the inner boundary of a diagonal groove 6 which extends completely across the body of the derailing block. The rib 5 also forms the outer boundary of a groove, 7 bounded on the extreme inner side by an upwardlyprojecting flange, 8.

The grooves 6 and 7 are for the reception of the flange of a wheel which is traveling over the derailing block in one direction or the other and they are so disposed with respect to the inclined ends 3 and 4 of the block that the load carried by the wheel does not come upon the flange running in either of these grooves.

In operation, when the block is upon a rail and the wheel approaches the inclined end 3, -the first operation is for the wheel to mount the inclined end until its flange has been lifted above the bottom of the advance end of the groove 6, whereupon the flange enters the groove 6 and impinges against the rib 5 which exerts a lateral pressure and causes the entire wheel to be shifted outwardly across the rail as the wheel travels forwardly. In case it is desired to back up a car over the derailer, the wheel tread runs up the inclined part 4 until the fiange is raised above the bottom of the groove 7, whereupon the flange is free to enter this groove and travel rearwardly along the same until it encounters the rib 5 over which it rides and allows the wheel tread to drop upon and ride down the inclined front end?) of the block.

The block is illustrated as mounted upon the rail directly at a joint therein, the two middle bolts of the rail joint being removed and being replaced by I bolts, 9 and 10. The block is provided with a series of clownwardly-projecting arms, 11, provided with openings registering with the eyes in the bolts 9 and 10; and a rod or shaft, 12, passing through these arms 11 and through the eyes in the bolts 9 and 10, serves to make a complete hinged joint between the rail and the block. If it be desired to attach the block at some other point than at a joint, the usual splice bars may be placed on opposite sides of the rail or else Stilt able washers may be placed on the I bolts to compensate for the missing splice bars.

The arrangement just described, forms a simple mounting which secures the block and maintains it in a definite relation with respect to the rail without requiring holes to be bored in the rail where it is possible to place the device at a joint; and at the same time it permits the block to be swung from an operative position above the rail to an idle position beside and below the rail.

In some instances it may be desired to lock the block in its operative position above the rail. This can conveniently be accomplished by providing one of the eye bolts and one of the adjacent arms 11 with suitable eyes, 13, through which the shackle of e a suitable lock, 14, may be passed. When 1 rail.

the lock is in position the block cannot be shifted by an unauthorized person.

In the arrangement shown I have illustratedalso a means for operating the block from a switch or signal tower and for looking the same. On a suitable shaft, 15, mounted in a housing, 16", supported by the ties so as to hold the shaft parallel with the rail are two b'ell crank levers, 17 and 18, to

the lower arms of which are connected operating or controlling rods, 19 and 20, respectively. The upper arms of the bell cranks. are connected to ears formed on indicated at 21 and 22. The ear 21 is connected to the bell crank lever 17 by means of a pair of links indicated at 23,

while theear 22 is connectedto the other bell crank lever by means of a pair of links indicated at 2 1.

In the arrangement shown, one of the rods, 19 and 20,- maybe used as an actuatingrod and the other as a locking rod; In the drawings the parts are shown the positions in which the block is locked in its derailing position. It will be seen that when both the rods 19 and 20'are-shifted so as to. swing. the bell crank levers 17 and18, (assuming of course that-thelock 14; has been-removed,) the block will be swung inwardly and I downwardly away fromthe V I claim 1.
